| hook | Had I known, I'd have come | Drop if and put Had, Should or Were before the subject. It sounds formal. | Bỏ if, đưa Had, Should hoặc Were lên trước chủ ngữ. Nghe trang trọng. |
| rule | The rule: Had I known = If I had known; Should you ... = If you ... · Were I = If I were | Drop if. Put had, should or were before the subject. Had needs a past participle. | Bỏ if. Đưa had, should hoặc were lên trước chủ ngữ. Had cần V3. |
| pair-had | Comes first | Say: Had I known, .... Had I not left, .... Should you ask, .... Do not say: If had I known, .... Hadn't I left, .... If should you ask, .... | Nói: Had I known, .... Had I not left, .... Should you ask, .... Không nói: If had I known, .... Hadn't I left, .... If should you ask, .... |
